Specification of Letters Patent.

Patented Dec. 6, 1921.

Application filed April 18, 1921. Serial No. 482,199.

To all whom it may concern:

Be it known that I, HARRY N. SoRENsoN, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Door-Butter; and I do hereby declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to door buffers, particularly of the type used in connection with the doors of automobiles, and has for its object the provision of a simple and improved device of this character which is inexpensive in construction, easy of application to a door and casing, and eifective in its operation in taking up play and looseness between the door and its casing and holding the door against rattlin The invention is 111 y described in the following specification, and While, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a fragmentaryside view of an automobile body with the door and its casing equipped with the invention and with the latter partly open and partially broken away. ig. 2 is an enlarged edge view of the socket member of the bufier and a portion of a casing member to which attached. Fig. 3 is an inner side view of said buffer member. Fig. 4 is an edge view of the buffer members in interengaged relation, and Fig. 5 is an outer side view of the projecting member of the bufler.

Referring to the drawings, 1 designates an automobile body having a door casing 2, and a door 3 mounted therein.

The socket member of a bufler embodying the invention is designated 4 and is preferably secured to the casing 20f the door opening. This member is preferably formed in U-shape from sheet metal or it may be cast or otherwise suitably formed, if desired, and forms a receiving socket 5 and has its leg members extended outward and then inward, as shown at 6, to provide a substantially U-shaped socket 7 at each side of the socket 5. The inner or rear end'of each of the sockets 5 is closed by an end part 8. The sockets 7 are intended to receive cushionblocks 9 of rubber or other suitable cushion material and project at their outer ends beyond the ends of the respective sockets in position to be engaged by the edge flange outer ends become moved outward a desli'ed extent to compensate for the wear and be held in such position by placing suitable shims between the inner ends of the blocks and the socket ends 8 as is apparent. The member 4 may be secured to the casing by screws 11 inserted through openings 1% in the base portion of the dovetail receiving socket 5 thereof.

The projecting member of the buifer comprises a plate 13 for attaching to a door edge by screws or in any other suitable manner and this plate has a block-like part 14 rigidly projecting outward from its face in position to extend transversely of the door edge to which the plate is secured. A metal band 15, preferably of substantially V-form is mounted around the block 14 and rigidly secured thereto by a pin 16 or in any other suitable manner. The leg portions of the band 15 are spaced laterally from a point near the nose portion of the block to the rear end thereof and the broadest part of the band 15,, which forms the projecting member of the butler, is slightly broader than the width of the socket 5, so that upon entering the same the free end portions of the band member legs are pressed inward by contact with the walls of the socket. The band 15 is made of spring material to facilitate such compressing action and it is preferable to provide a cushion block 1? of rubber or other suitable yielding material between each le of the band 15 and the portion -of the bloc 14 from which it is spaced. The free ends of the band 15 are turned inward around the ends of the block 17 to prevent a withdrawal of the cushion block from their respective pockets lengthwise or" the dove-tail. The blocks are prevented from transverse re moval from their pockets by a cross piece 18 which is secured to the block 1% and overlaps the cushion blocks 1?.

It is evident that l have provided a simple, elficient and inexpensive form of buffer, the

I wish it understood that my invention is not limited to any specific construction, ar-

parts, as it is modifications and changes without departing from the spirit of the claims.

3. A door bufier having its socket memberprovided with sockets at opposite. sides thereof and door cushion blocks adjustably mounted in the sockets and projecting from their outer ends.

4. A door bufier having its socket member formed in U-shape to form a receiving socket extended outward and inward to form sockets at opposite sides of the'receiving socket, all of said sockets having open outer ends and the side sockets having closed innerends, and door cushion bumper blocks adjustably mounted in the side sockets with their outer ends projecting beyond the sockets and their inner ends thrust against the closed ends of the side sockets.
